Specification of Letters Patent.

Patented Feb. 17, 1920.

Application filed December 27, 1918. Serial No. 268,455.

To allee/1,0m t'mag/ concern:

Be it known that I, Gnoncn lV. Srnni, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Combined Ventilatore and Screens, of which the following is a specification.

This invention relates to ventilators for windows and other openings.

The object of the invention 'is to provide a combined ventilator and screen which is rustproof, simple, cheap and practical.

Another object is to so construct a ventil: lator that it will not break or mar the windows in connection with which it is used and which may be bought in strips and easily cut to t any width window.

Another object is to provide a ventilator which may be used at the top, center or bottom of a window a-nd perform the double function of a ventilator and screen for iiie., other insects and dust. Y

lWith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the conibination a-nd arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a front elevation of the upper portion of a window equipped with one form of this invention,

Fig. 2 is a vertical transverse section through the ventilator,

Fig. 3 is a similar view showing a slightly different form of the invention,

Fig. 1 is a detail perspective view of the ventilator shown in Figs. 1 and 2 with the parts arranged in partially folded position,

Fig'. 5 is an enlarged front elevation of a portion .of a ventilator showing a slight modification of the invention, and

Fig. 6 is a detail transverse sectional view of the form shown in Fig. 5.

In the embodiment illustrated in Figs. 1. 2 and '-1, a ventilator 1 is shown composed of a sheet of cardboard folded longitudinally at 2 and 3 equal distances apart to form sections il, 5 and 6, the section 5 being arranged between the folds 2 and 3, while section v6 is adapted to be positioned between sections 4 and 5 as is shown clearly in Fig. 2. The middle or intermediate section 6 is provided with a plurality of closely arranged perforations 7, while the outer sec-- tions 4 and 5 have large apertures S which may be of any desired configuration, but are here shown circular. These apertures 8 in sections 4L and 5 are so positioned that when the sections are in folded operative position they will be arranged opposite each other with the perforated section 6 between them so that air may circulate through the per forations and apertures without admitting dust or insects into the room in connection with which the device is used.

Then the sections l., 5 and 6 have been folded in close contact with each other they are .stitched along .one edge as shown at 9 and are creased or folded along the line 10 after being so connected. This fold forms a flange-11 which is designed to engage thc window frame so as to exclude all particles of dust which might otherwise enter and which insures a close fit of the ventilator in the. frame. The sections e, 5 and 6 after being so folded are also preferably stitched through as shown at 12 to securelyhold the sections together and form a rigid nonyieldable screen.

The cardboard of which this combined screen and ventilator is composed is ren-- dered waterproof, preferably by enamelingI it on one or both faces and this enamel may be of any desired color to correspond with the shades in the room in connection with which the ventilators are to be used, or they may be colored to correspond with the woodwork at the option of the pur- Chaser, also assists in rendering the screen d suiiiciently rigid to withstand all strains to which it will be subjected. It is to be understood that large supplies of this material are kept on hand to be sold in strips.

In the form shown in Fig. 3, the ventilator 11L is composed of a strip of cardboard folded at 13 to compose two outer sections 14; and 15 having registering apertures 16 therein. These apertures 16 are similar to the apertures 8l used in the other form. The free ends of the sections 14 and 15 are stitched together as shown at 9 and folded at 10 to form an attaching or bearing ange 11.. Clamped between the sections 14: and 15 is an intermediate section 17 composed of rnon-'rusta'ble foraniin-ous :material preferably of textile fabric, Which acts as a strainer to prevent the 'passage ofV dust through theregistering apertures 16 and yet perniit'the free circulation of air .therethrough. -Any desired color may be used A"for :this jstra-ining` fabric, either to correspond lWith or contrast with the colors used on the outer sections 14 Y'and 15. tilators lau are used in the saine manner that those 'shown in Fio's. '1, 2 Yand 4 are einployed'and are pre'ierabl-y v'manufactured in 'long'fstrips-or rolls and cut orf in Alengtlisto suittljie purchaser.v i

In 4the forin'shownfin Figs. `5"and 6, the structure is'the saine as that :shown in Fig. 3,eX'cept `that rivets '1S fof copperjor nonlrustalole material are `used, vfor securingthe Vsections togethr as is :shown dearly in Fig. "6. Y

vWhile Ihave mentioned cardboard as-tlie Vmaterial from Which'these ventilators areto beconst'ructed, it is obvious that this terni is intended to cover heavy thick paper,

which "ivhen coated With ena-hiel will have suiiicient rigidity to resistail strains' ltoV vhich'it will `he'subject'ed an'd'it isa-lso obvious'thgitfwhile stitching and frivets are shown for lsecuringthe sections together, it

.'Froin Athe kabove description it lvvil-lbe 0bs obvious'that they inaybeotherwise lsuit- *viousfthat veiitilators and screens constructed asdescribed endshown VWill -be very cheap toinanufacture vand very eiiicient 1n operation, since they will not'in'ar or injure either the'tvindo'w sash or fraine in connectinfWith 'which they'are used, being rustproof and lthat vthey may be'readily cutk by scissorsor a knife into desired lengths, to `fit Windows of different Widths and when 'so cut,iaii'ges f19`iney be formed at the op-V posite Vends of the strips cut off for engage- -nient vvth the side'nieinbes of lthe Window These veni fraine 4I lin connection-With which they are to beused.
